We model the circumstellar medium surrounding SN 1987A in the equatorial region, using 1 and 2 dimensional numerical simulations. Data from X-ray, radio and optical observations gathered over the past 20 years is used to compute the structure of the surrounding medium as carved out by winds from the progenitor star. We then compute the evolution of the SN shock wave within this medium, and the emission resulting from the interaction of this shock with the circumstellar medium. We discuss our results in the context of the observations, and make predictions for the future evolution of the shock wave.
